Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, specifically, it demonstrates a stator feeding device for motor manufacturing. Background Technology

[0002] The rotor is an important component of an electric motor. An electric motor is assembled from a shaft and a stator. During the production and processing of an electric motor, when assembling parts of the stator and transferring them between processing steps, the stator body needs to be transported to a conveyor line for the next processing step. Currently, the transfer of stators is usually done manually by workers. Due to the limited speed of manual operation, it is impossible to coordinate with the continuous operation of automated equipment or robots, which can easily cause bottlenecks in the production process and reduce overall production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a stator feeding device for motor production, which has a simple and practical structure and can work in conjunction with automated equipment or robots.

[0004] The technical solution is as follows: A stator feeding device for motor manufacturing, comprising: Machine tool; The rotating spindle is mounted vertically on the machine base and its rotation is achieved by a power supply mechanism. The turntable is connected to the rotating spindle in a horizontal position, and the center of the turntable coincides with the center of the rotating spindle; Two carriers are detachably placed on a turntable. Each carrier has several product seats arranged in a spaced array. The product seats are used to place the stator, so that the stator is in an upright position.

[0005] In addition, the above embodiments of this utility model may also have the following additional technical features: According to one embodiment of this utility model, the power supply mechanism includes a rack, a gear, a cylinder, and a support. The cylinder and support are respectively disposed on the machine base. The rack is movably mounted on the support, with one side of the rack connected to the drive end of the cylinder. The gear is disposed on the rotating main shaft and meshes with the rack. The cylinder drives the rack to perform linear reciprocating motion, which in turn drives the gear to rotate, thereby driving the main shaft and the turntable to rotate, converting linear motion into rotational motion, and realizing the adjustment of the turntable angle.

[0006] In one embodiment, a slider is provided on the support, and a slide rail is provided on the back of the rack. The slider is slidably connected to the slide rail in a snap-fit ​​manner. The cooperation between the slider and the slide rail provides high-precision guidance and support for the linear motion of the rack, ensuring smooth rack transmission and improving transmission accuracy.

[0007] According to one embodiment of this utility model, the machine base is provided with several mounting seats arranged around the rotating main shaft. A ball bearing roller is provided on the top of each mounting seat, and the rolling element of the ball bearing roller makes rolling contact with the bottom surface of the turntable. Adding multiple ball bearing rollers as auxiliary support points can prevent the turntable from wobbling due to its own weight or uneven load, ensuring it always maintains a horizontal rotation state.

[0008] According to one embodiment of this utility model, the machine base is provided with two bases located on both sides of the rotating spindle. A buffer body is provided on each base, and a blocking body is provided on the bottom surface of the turntable. During the rotation of the turntable, both sides of the blocking body can contact the buffer body respectively. Through the collision between the blocking body and the buffer body, the rotation angle of the turntable is physically limited, allowing the turntable to rotate only between two positions, precisely rotating the carrier to the corresponding working position.

[0009] In one embodiment, the line connecting the centers of the two bases passes through the rotation center of the rotating spindle, and the buffer bodies on the two bases are oriented in the same direction. This allows the turntable to rotate only between these two positions, i.e., 180°, thus achieving the position swapping of the vehicle.

[0010] According to one embodiment of this utility model, the product holder includes a boss and a positioning ring. The boss is disposed on the carrier, and the positioning ring is disposed on the boss. The positioning ring is cylindrical and its diameter is adapted to the inner diameter of the stator. The positioning ring is inserted into the inner hole of the stator, realizing precise radial positioning of the stator and ensuring that the position of each stator on the carrier is unique and consistent.

[0011] According to one embodiment of this utility model, the turntable surface is provided with a plurality of positioning pins, and the carrier is provided with a plurality of positioning holes into which the positioning pins can be inserted one-to-one. This ensures that the position of the carrier remains fixed each time it is placed on the turntable.

[0012] In one embodiment, handles are provided on both sides of the top surface of the carrier. The handles enable workers to safely and effortlessly perform the handling and loading / unloading operations.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The turntable can be adjusted in angle. When a carrier is loading or unloading stators at a certain station on the turntable (such as the loading and unloading station) by a person or a robot, another carrier can be located at another station on the turntable (such as the picking station) and picked up by a robot. This cycle is repeated to complete the batch transfer of stators.

[0014] 2. A single carrier can load multiple stators at once, meeting the material supply needs of continuous and high-speed production of automated equipment and reducing the number of frequent loading and unloading operations.

[0015] 3. The motor stator needs to maintain an upright posture in many processing and assembly processes (such as wire insertion, rotor installation, etc.). This design allows the stator to maintain the final required state from the material feeding stage, making it easy for robots or equipment to directly grasp and perform subsequent operations without the need for additional posture adjustment mechanisms, thus simplifying the process.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model embodiment proposes a stator feeding device for motor production, see reference. Figure 1 As shown, the system comprises a machine base 1, a rotating spindle 2, a turntable 4, and two carriers 5. The rotating spindle 2 is vertically mounted on the machine base 1 and is rotatably mounted at the center of the machine base via bearings. The rotating spindle 2 is rotated relative to the machine base 1 by a power supply mechanism 3, which is located on the machine base 1. The turntable 4 is horizontally connected to the top of the rotating spindle 2, and the center of the turntable 4 coincides with the center of the rotating spindle 2. The rotating spindle 2 drives the turntable 4 to rotate. The two carriers 5 are detachably placed on the turntable 4 and arranged side by side. Each carrier 5 has several product seats 6 arranged in a spaced array, i.e., multiple rows and columns of product seats. The product seats 6 are used to place stators, which are positioned vertically.

[0019] This embodiment adopts a vertical rotary design, which, compared to a linear conveyor line, allows for station switching within a limited planar space. The layout is compact, with two carriers designed on the turntable. When one carrier is at a station on the turntable (such as a loading / unloading station) where stators are being loaded or unloaded by a person or a robot, the other carrier can simultaneously be at another station on the turntable (such as a material picking station) where a robot picks up materials. Afterward, the turntable rotates, causing the positions of the two carriers to switch. The empty carrier continues to load stators, while the full carrier picks up materials. This cycle is repeated to complete the batch transfer of stators.

[0020] See Figure 2 As shown, the power supply mechanism 3 includes a rack 31, a gear 32, a cylinder 33, and a support 34. The cylinder 33 and the support 34 are respectively mounted on the machine base 1, while the rack 31 is movably mounted on the support 34 in a lateral position. One side of the rack 31 is connected to the drive end of the cylinder 33. The gear 32 is located in the middle of the rotating main shaft 2 and meshes with the rack 31. The cylinder drives the rack to perform linear reciprocating motion, which in turn drives the gear to rotate, thereby driving the main shaft and the turntable to rotate, converting linear motion into rotational motion, and realizing the adjustment of the turntable angle.

[0021] Compared to solutions using servo motors and reducers, the cylinder + gear rack solution is lower in cost, simpler in structure, and has a lower technical threshold for factory maintenance personnel, making it easier to maintain and replace spare parts.

[0022] The rack 31 has a slider 35 mounted on the support 34 and a slide rail 36 mounted on its back. The slider 35 is slidably connected to the slide rail 36 by a snap-fit ​​mechanism. The cooperation between the slider and the slide rail provides high-precision guidance and support for the linear motion of the rack. The combination of the slider and the slide rail effectively prevents the rack from jumping up and down or deviating left and right during movement, ensuring smooth rack transmission and improving transmission accuracy.

[0023] Referring to the figure, at least four mounting seats 7 are provided on the machine base 1, arranged around the rotating spindle 2. The four mounting seats 7 are rotationally symmetrically distributed with the rotating spindle 2 as the center. Steel ball rollers 71 are provided on the top of the mounting seats 7, and the rolling elements of the steel ball rollers 71 are in rolling contact with the bottom surface of the turntable 4. The total weight of the turntable, carrier, and stator may be very large. Relying solely on the bearings at the bottom of the rotating spindle for support would place an excessive load on it, affecting rotational flexibility and lifespan. Therefore, multiple steel ball rollers are added as auxiliary support points to distribute the weight across the machine base. The combined action of multiple support points can prevent the turntable from wobbling due to its own weight or uneven load, and always maintain a horizontal rotation state. This is crucial for the stable placement and precise positioning of the stator. Furthermore, the rolling friction contact between the steel ball rollers and the turntable reduces the driving force required for rotation, making cylinder drive easier, movement smoother, and reducing impact and vibration.

[0024] See Figure 2 As shown, two bases 8 are respectively located on both sides of the rotating spindle 2 on the machine base 1. A buffer body 81 is installed on the base 8, and a stop body 41 is installed on the bottom surface of the turntable 4. During the rotation of the turntable 4, both sides of the stop body 41 can contact the buffer body 81. The buffer body is typically a damper. Through the collision between the stop body and the buffer body, the rotation angle of the turntable is physically limited. This allows the turntable to rotate only between these two positions, precisely rotating the carrier to the corresponding working position. This mechanical limiting method is very reliable, low-cost, and does not require electronic sensors or complex control systems to determine the position.

[0025] The line connecting the centers of the two bases 8 passes through the rotation center of the rotating spindle 2, and the buffer bodies 81 on the two bases 8 are set in the same direction. This means that the turntable can only rotate between these two positions, i.e., 180°, which just achieves the position swapping of the vehicle.

[0026] See Figure 3 As shown, the product holder 6 includes a boss 61 and a positioning ring 62. The boss 61 is located on the carrier 5, and the positioning ring 62 is located on the boss 61. The positioning ring 62 is cylindrical, and its diameter is adapted to the inner diameter of the stator. The boss is designed to be large enough to support the stator, and its thickness is not too large. The positioning ring is inserted into the inner hole of the stator, and the stator is easily fitted in, achieving precise radial positioning of the stator and ensuring that the position of each stator on the carrier is unique and consistent.

[0027] See Figure 3 As shown, the surface of the turntable 4 is provided with several positioning pins 42, and the carrier 5 is provided with several positioning holes 51 into which the positioning pins 42 can be inserted one by one. This ensures that the position of the carrier is fixed every time it is placed on the turntable, and that the engagement of the pins and holes prevents the carrier from sliding or twisting on the turntable surface due to inertia during the start-up, stopping and rotation of the turntable, thus ensuring the stability of the turntable during operation.

[0028] The carrier 5 is equipped with handles 52 on both sides of its top surface. The handles enable workers to safely and effortlessly carry out the handling and loading / unloading of the carrier, and also make it easier for workers to align the carrier and place it on the positioning pin of the turntable, or lift it from the pin.

[0029] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
